Magic!

> And which [CLI commands](https://docs.ipfs.io/reference/api/cli/) make relation between Qm\_HASH\_ and _subdomainHASH_ ?

The Qm hash is a CidV0 Content Identifier (CID) which uses base58 encoding.

The subdomain hash is a CidV1 content identifier which uses base32 encoding. It is the same underlying hash, just represented differently.

You can covert between hashes using `ipfs cid` commands. `ipfs cid base32 <QmHash>` for example.
